PiJuice HAT – A Portable Power Platform For Every Raspberry Pi

Share this:

As one of the smallest systems around there are so many amazing things you could do with the Raspberry Pi if it was self-powered and portable. Introducing PiJuice! A fully uninterruptable power supply that will always keep your Raspberry Pi powered.

Our revolutionary PiAnywhere technology – contained in every PiJuice HAT - is the best way to take your Pi off the grid! The real time clock (RTC) on board will let your Pi know what time it is even with no power input or internet connection. Alongside this is an integrated microcontroller (MCU) chip which will manage soft shut down functionality and a true low power deep sleep state and intelligent startup.

You will be able to always keep track of the charge levels and other info with the two built-in tri-coloured RGB LEDs, trigger events and scripts with the three programmable buttons and since the PiJuice will use up to just five of your GPIO pins (just power and I2C), the rest are free to diversify your project. The stacking header allows you to continue to use your existing HATs and add-ons with PiJuice.

Ultimate integrated power is one thing but what if we could make the Raspberry Pi renewably powered too? Solar, wind, thermoelectric and other renewable power is free, clean, and green and we’re proud to have developed an affordable and efficient renewable power solution for the Raspberry Pi! PiJuice is self-monitoring and, like a space satellite, can become a completely autonomous system. Use the PiJuice as part of an autonomous camera system, weather stations, off-grid desktops, and so many other great outdoor projects. View and buy the PiJuice solar panels separately here.

PiJuice Features:

Onboard 1820 mAh “off the shelf” Lipo / LiIon battery for ~4 to 6 hours in constant use! (with support for larger Lipo Battery of 5000 or 10,000 mAH+ to last up to 24 hrs +)

A Full Uninterrupted / Uninterruptable Power Supply solution.

Designed for the Raspberry Pi A+, B+, 2B and 3B but also compatible with Raspberry Pi Zero v1.3 and Wireless.

Compatible with any 4 pin battery on board that can be used with 00-9155-004-742-006 battery contacts from AVX including the BP7X, BP6X, and any compatible batteries including the 1600mAh and 2300mAh ones from CameronSino (CS-MOA853SL and CS-MOA855XL)

There is an on board 4 pin screw terminal block for larger off board batteries. Any single cell LiPo / LiIon is compatible. However, you use your own sourced battery at your own risk. We HIGHLY RECOMMEND using a battery with an internal protection circuit and a NTC (temp sensor)

Output amperage - maximum current at 5V gpio is 2.5A and at VSYS output 2.1A, but also this depends heavily on battery capacity. For BP7X have measured around 1.1A at 5V GPIO and around 1.6A at VSYS output. Obviously, this also depends heavily on the current draw demanded by the Raspberry Pi/device itself. To achieve a maximum of 2.5A it will need battery over 3500mAh.
